To reduce cost in a home delivery industry and increase convenience for a home delivery recipient by preventing unnecessary re-delivery caused by the missing hearing of a chime sound even the recipient is at home.SOLUTION: An indoor notification is continued even if there is no further operation left after performing indoor notification based on an outdoor operation of a visitor. A visitor notification device is provided in the vicinity of a resident, as an indoor apparatus support, as well as a visitor notification relay device which detects the occurrence of a visitor notification sound from the indoor apparatus to relay to the visitor notification device. The visitor notification device continues a visitor notification even if information relay from the visitor notification relay device stops. The visitor notification relay device relays by consuming power obtained by harvesting the vibration energy of a visitor notification sound. In the event of the shortage of a harvest charge voltage, harvest power is accumulated by a plurality of outdoor operations. The visitor notification relay device switches on communication based on the detection, so that the visitor notification device responds and starts a visitor notification to continue the notification even when the communication is interrupted. As the visitor notification device, either a mobile telephone is diverted or an electric outlet plug-in type is prepared.SELECTED DRAWING: Figure 1
